The formula structure of eye shadow is roughly the same as that of foundation. The difference from foundation and powder products is that eye shadows are richer in color and often have additional gloss and other effects, so the selection of coloring pigments and pearlescent pigments is wider and more variety, in addition, the skin around the eyes is relatively fragile. The colorant selected must be non-irritating. Commercial eye shadows are often compounded by inorganic pigments, organic pigments, pearlescent pigments, brighteners, etc. to form a variety of colorful products.
